Question

The drawing shows a human figure approximately in a
sittingposition. For the purposes of this problem, there are three
partsto the figure, and the center of mass of each one is shown in
thedrawing. These parts are: (1) the torso, neck, and head (total
mass= 42.6 kg) with a center of mass located on the y axis at a
point0.376 m above the origin, (2) the upper legs (mass = 19.3 kg)
witha center of mass located on the x axis at a point 0.166 m to
theright of the origin, and (3) the lower legs and feet (total mass
=10.2 kg) with a center of mass located 0.472 to the right of
and0.300 m below the origin. Find the (a)
xcoordinate and (b) the y coordinate of the
centerof mass of the human figure. Note that the mass of the arms
andhands (approximately 12% of the whole-body mass) has been
ignoredto simplify the drawing.
